[image]Sierra Negra Erupts - NASA image created by Jesse Allen, Earth Observatory, using data provided courtesy of courtesy of Eric Fielding (NASA/JPL), the NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team
The Sierra Negra Volcano in the Galapagos Islands began erupting on October 22, 2005. In early November, Sierra Negra’s lava flow was so hot it could be seen at night—by a thermal infrared satellite sensor, that is. On November 2, 2005, the Advanced Spaceborne Thermal Emission and Reflection Radiometer flying onboard NASA’s satellite captured this nighttime image of the volcano.This false-color image shows the summits of the Sierra Negra Volcano (“Black Mountain Range”) in the east and...

[image]The Continuing Eruption of Mt. Etna - Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan
Located near the east coast of Italy's province of Sicily, Mount Etna is Europe's most active volcano and is one of the world's largest continental volcanoes, standing about 3,350 m (10,991 feet) tall. Mount Etna has a broad base (or shield) spanning roughly 60 by 40 km (36 by 24 miles) and reaching an altitude of about 2,900 m (9,500 feet). The remaining 400 m (1,200 feet) at its top is a stratovolcano made from several vents that have coalesced.Most of the surface of Mount Etna is covered by h...

The rising sun bathes the eastern half of Russia’s Kamchatka Peninsula with light, casting long shadows in the west. The shadows highlight the plume of ash that continues to rise from the Klyuchevskaya Volcano. The largest and most active volcano on the peninsula, Klyuchevskaya has erupted regularly since its first recorded eruption in 1697. Its most recent activity began in mid-January 2005, and has not abated...

The Klyuchevskaya Volcano is the highest volcano on northeastern Russia’s Kamchatka Peninsula. The 4,750-meter (15, 584-foot) peak is also the peninsula’s most active. A new phase of eruptive activity began in January 2005, with seismic activity higher than normal and repeated ash and steam plumes. On February 21, the Kamchatkan Volcanic Eruption Response Team reported that an eruption of Klyuchevskaya had produced a lava flow down the northern flank of the volcano that melted a large portio...

The southern tip of South America tapers off into a collection of rugged islands known as Tierra del Fuego. The southernmost headland in this archipelago (group of islands) is Cape Horn. Before the completion of the Panama Canal, ships had to “round the Horn” in order to move goods or people from the Atlantic side of North and South America to the Pacific. The area is notorious for its sailing hazards: strong winds, large waves, and icebergs drifting up from Antarctica.This image from the Ad...

At bottom left in the full, high-resolution scene, the streets of Tucson make cross-hatched lines across the arid terrain, while at far upper right, green vegetation is gr...

[image]Three Gorges Dam, China - Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan
The above image shows a 60-kilometer stretch of the Yangtze River in China. In the image, one can see the Xiling Gorge, which is the easternmost of the three big gorges along the Yangtze. The construction site of the Three Gorges Dam, slated to be the world’s largest, sits on the left-hand side of the image along the big bend in the river. The dam is being built in part to control flooding along the Yangtze.This image was acquired on July 20, 2000, by the Advanced Spaceborne Thermal Emission a...

[image]Fires in Southern California - Image courtesy U.S./Japan ASTER Science Team.
This Advanced Spaceborne Thermal Emission and Reflection Radiometer image reveals the scorching fire fronts of the Old and Grand Prix Fires that raged in the San Bernardino Mountains at the end of October 2003. The image combines infrared, near infrared, and green wavelengths (ASTER bands 4, 3, and 1). Vegetation is green, burned area is reddish, smoke is blue, and the blazing fire front is hot pink...

[image]Burn Scar from Southern California Fires - Image courtesy Jesse Allen, based on data from the U.S. /Japan ASTER Science Team.
This false-color image shows the devastating burn scars left behind by wildfires in southern California in late October 2003. In the image, unburned vegetation appears red, while burned areas appear charcoal-brown. The image, captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on November 2, 2003, shows the Santa Monica Hills in the Thousand Oaks and Simi Valley regions of California northwest of the city of Los Angeles...

[image]Rare Snow in and around Tokyo - NASA image courtesy the NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team
Snow is a rare sight in Japan’s capital city, Tokyo. But on January 25, 2006, snow is exactly what the Advanced Spaceborne Thermal Emission and Reflection Radiometer saw when it acquired this image. The city was hit with a rare snow storm on January 21. As much as 3.5 inches fell in the center of the city, reported the Agence France-Presse. To the east, nearer the Pacific, enough snow fell to close the Narita Airport, stranding thousands of passengers.Bright white snow mixes with dark green ve...

[image]Erebus Ice Tongue: Image of the Day - NASA -- NASA image created by Jesse Allen, using data provided courstesy of NASA/GSFC/METI/ERSDAC/JAROS, and the U.S./Japan ASTER Science Team.
The Erebus glacier in Antarctica comes down from Mt. Erebus and protrudes off the coast of Ross Island, forming an 11-12 km long ice tongue -- a long and narrow sheet of ice projecting out from the coastline. The Erebus Ice Tongue is the serrated, blue-rimmed ''knife'' extending toward image center from the upper right out into snow- and ice-covered McMurdo Sound. Beneath the smooth white expanse is the Southern Ocean...

[image]Dust Storm in Southern California: Image of the Day - NASA -- NASA image created by Jesse Allen, using data provided courtesy of the NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan asterweb.jpl.nasa.gov/ ASTER Science Team.
Along historic www.historic66.com/ Route 66, just southeast of the little town of Amboy, California, lies a dried-up lake. Dry lakebeds are good sources of two things: salt and dust. In this image, the now-parched Bristol Lake offers up both. On April 12, 2007, dust storms menaced the area around Amboy. To the northwest, near Newberry Springs, California, dust hampered visibility and led to a multi-car collision on Interstate 40, killing two people and injuring several others...
